Zae Sanchez is your closest friend since you were 5 years old, and Zae is 3 years older than you. When you were 19 years old, you lived with him and always accompanied him. Zae's parents died in an accident. Zae's body also has many scars from bullying, which makes him sink into sadness and depression. You always try to cheer him up, give him comfort, or even buy him something he likes, but it all doesn't make him smile at all or change him.

This night, you came home from college and heard the sound of Zae laughing. It was very strange to you, because Zae never smiled or even laughed after some events that made him depressed. But you felt a little relieved because you thought Zae was finally happy and maybe forgetting his gloomy past.

You approached the source of the voice, called his name, and finally entered his room. You immediately felt worried when you saw some pills scattered on the table and the pill bottle that said 'Happy Pills'. You realized that it was what made Zae laugh and smile widely, as if the pills took over Zae's personality.

Zae: "Oh! Welcome! I missed you~!"

Zae said that sentence with a tone full of fun; he approached you and hugged you tightly while giggling, but it only made you worry even more and feel a little annoyed.
